IMPROVED SAFETY OIL-CAN.

Specification forming part of Letters Patent No. 45.340, (lated December 6, 1864.

To @ZZ whoml it may concern.,A

Beit known that we,- JoHN M. PERKINS and MARK W. HOUSE, of Cleveland. in the county of Cuyahoga, in theState of Ohio, have invented anew and useful Oil-Can. so constructed as to prevent the explosion of the same by the igniting of inflammable liquids contained within the can; and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and the letters of reference marked thereon.

The nature of our invention consists in plac ing or forming withiuthe neck or spout ofthe can a series of tubes or passages.

Figure I shows the neck-piece and base of the spout screwed together, and a portion of both pieces removed to show the longitudinal passages through the inner piece.

The same letters indicate the same parts in both gures.

A, Fig. I in the drawings, is the body of the can; B, the top of the can; C, the neckpiece; d, the base of the spout; g, the venttube; f f f f, Fig. II, the tubes or passages through which the liquids i'low in discharging the contents ofthe can. These passages, whose diameters are proportioned to their lengths are to be constructed of such a size that iiame will not pass through them. Openings oneAsiX- teenth (51%) of an inch in diameter and onehalf(5) inch long have been found to resist the passage of flame perfectly. XVe prefer this size, as affording a free passage to heavy oils. Larger openings than one-sixteenth (9,-.) of an inch require to be proportionally increased in length.

In the construction of a can upon our plan we feel assured that it possesses decided advantage over Wire-gauze, which may be used for the same purpose. To make a can perfect-ly safe against explosions by the use of wiregauze, it is necessary that it should be very fine, thus offering resistance to the ready ilow of oils, and more especially when they conchilled by a low temperature; and again, it often happens that chemicals, glue, and other foreign substances are found in oils improperly put upon the market. All these would tend to clog small apertures, and under certain conditions Vwould render such a can nearly useless; but in one constructed upon our plan we obviate these diflculties. Should these pas tain an undue amount of paraiine or become sages ever become foul or obstructed, they are'
